ACTUATING MECHANISM FOR WORK SUPPORTS.

Application filed March 11,1919. Serial No. 281,939.

T 0 all whom it may concern:

Be it known that I, JOHN M. BENJAMIN, a citizen of the United States,residing at Beverly, in the county oi Essexand State of Massachusetts,have invented certain Improvements in Actuating Mechanism for forkSupports, of which the following description, in connection with theaccompanye ing drawings, is a specification, like reference characterson thedrawings indicating like parts in the several figures.

This invention relates to actuating mechanism 'li'or work-simports, andparticularly to those associated with machines for attaching loadedheels, or those in which the heels operated on carry nails for affixingthem to shoes. In heelnttaching machines of the type illustrated inUnited States Letters Patent No. 1,157,688, Glidden, October 26, 1.915,in'which heels and top-lifts are secured to shoes by nails supplied tothe machine, it is customary to shift the heel and top-lift support fromits top-lift-attaching to its heel-attaching position under theinfluence of the nail-transferring mechanism when this is moved from thedistributing mechanism to deliver its load ofnails to the nail-block ortemplet of the machine. With loaded heels, however, thenail-transferring mechanism is not used, and the body portion of theheel is usually placed directly upon the nail-block.

Under such conditions as are abo-ve outlined, an object of the presentinvention is to Furnish means for actuating a support at the correcttime in the cycle of operations. In the attainment of this object, Iprovide, in a machine having a plurality of movable work-supports, meansfor moving one of said supports from another in one direction only,movement in another direction being preferably under the influence ofactuating means. In the illustrated embodiment of the invention.connections between the shoesupport, or jack-post, and the heel-portion-Support, or swing-plate, cause them to move together, the preferredrelation being, that when the jack is carried to its non-operatingposition to enable a fresh piece of workto be supplied, the swing-plateis shifted from its top-lift-attaching to its non-attaching position,the latter being that in which the body of the heel is secured to theshoe. The opposite movement of the support, as that of the swing-platein which it co-operates with thejack, is efiected by the previouslymentioned actuating means and under the control of theassociatedsupport, or jack. The moving means and actuating meanspreferably have elements in common. To permit a variation in position ofa support without effect upon the companion support which receivesmovement from it, the moving means, or connections between the supports,have provision for'allowing such variation. When the invention isembodied in a heel-attaching machine, the horizontal adjustn'ient of thejack, to correctly locate the work with respect to the nail-block, maybe provided for by a shifting pivot in the connections to theswing-plate; while the vertical travel or work-positioning movement ofthe jack is caused to be without ill efiect upon the mechanism of thisinvention bythe presence of a connecting element long in comparison'with the travel. To insure the correct relation of the support and theassociated elements, I furnish means to vary the extent of its travel,as by including an adjustable element in the connections through whichthe movement is efi'ected. I

In the accompanying drawings,

Fig. 1 is a side levation of a portion of the machine including oneembodiment of my invention;

Fig. 2 is an enlarged horizontal section on the line 2-2 of Fig. 1; and

Fig. 3 is an enlarged perspective view of the elements more closelyconcerned with this invention.

In its general characteristics, the machine herein illustrated issimilar to that disclosed in the previously mentioned patent, thenaildriving mechanism not appearing. As to the elements more directlyco-operating with the work, a jack-post 10 for supporting a lasted shoe,indicated at S, is pivoted at 12, for movement between operating andnonoperating positions, upon a slide 14 adJustably mounted for movementfrom front to rear of the machine in a head 16. This head is carried bya vertical rod 18, arranged for reciprocation in a bearing in the frame20 and articulated at its upper extremlty to a top-lever 22 fulcrumedupon the frame. The top-lever and connected jack are oscillated by a rod24 joined tothe power-shaft of the machine, this latter element notbeing shown.

Pivoted as usual upon the cross-head 26, above the nail-block .ortemplet 28, is a swing-plate for supportinga heel-portion, in thepresent instance a top-lift, which is to be attached to a jacked shoe,this heel-portion of the work beingcarried by a suitable holder 34. by arod 36 to a rock-shaft 38, journaled vertically at the rear of the frameand having connectedto it an actuatingdevice, as ahelical spring 40,which shown as encircling the rock-shaft, and so connected as to exertits tension to move the swing-plate from a position clear of thenail-block,when the'heel iscarried upon said block, to that in whichthetop-lift is located below the shoe. The swing-plate is temporarilyretained in the first, or inactive, position by a latch 42 mounted on anarm .3, fixed to therock-shaft and arranged to engage an elementcarriedby the frame. Cooperating with this latch is a tripping device44,

mounted upon a bracket 46 secured upon the jack-actuating rod 24. lVhenthe rod 24 moves upwardly at the beginning of the heel attaching;operation, the tripping device passes idly by the latch, but, on thereverse in ovemient, the device 44 frees the latch and allows the swingplate to travel to its top-lift-attaching position.

To move theswing-piate in the opposite direction, or fronrthetop-lift-attaching position tonne clear of the nail block, whenthespring'40 istensioned and the swingplate is latched, the followingmoving or conneoting means is provided. Fulcrumed at a' convenient pointupon the head 16 adjacent to the pivot pin 12 of the jack-post, is alever 48, preferably in the form of a bell-crank having a rearwardlyextending arm50 and an upwardly extending arm The arm 50 is pivoted at541 to a projection- 56 from the jack-post, which projection may consistof an extensionof the arm to which is connected. the chain 5801? theband-clamp 60: The arm 52 of thelever 48 is joined by a rod 62 to alever 64: fulcrumed at 66 upon the frame ofthe machine. Thislast-mentioned lever is forked at (38, the arms eX-' te'nd-ing'atopposite sides of the rod 36. Adjacent to the fork, the rod is threadedat 70,

= and adjustably mounted upon this threaded por-tion'isa contact memberor disk 72 the rear face-of which rests against curved edges 74 of thefor-in- A-fter the completion of'a heel-attaching operatio'n,=the swing,plate is in the position illustrated in' Fig. 2 of the drawings, withthe top-lift holder 34 in'itsactive relation; As the jack-post is swungout by the operatonto-the angle shown in Fig. 1 for the pur Theswing-plate is connected pose of removing the heeled shoe and supplyinganother lasted shoe for the heeling operation, the projection'56 fromthe jack post rocks the lever d8 upon its fulcrum, movin the rod 62rearwardly, this in turn, through the lever 64, pressingthe edges 74: ofthe fork against the contact-disk 72 Consequently, the rod 36 travelstoward the front of the machine, moving the swing plate about its pivotin an anticlockwise di rection as viewed in Fig. 2, until the swingplate is retained by the latch 4:2 clear of the nail-block. Aspreviously indicated, this relation is maintained until theheel-attaching operation is completed, when the tripping device 4.4releases the latch and the swing-plate oscillatesto thetop-lift-attaching position under the influence of the spring 40. i

To enable an adjustment of the jack post from front to rear of themachine, or in the reverse direction, to be made without affecting theextent of movement of the swingplate, the pivot pin 54 operates in aslot 76 extending longitudinally of the arm 5(h0f the lever 48 and, whenthe jack is at its extreme of forward travel, this slot is substantiallyhorizontal. It will be evident that the shifting of the pin in the slotwill cause the swinging out of the ack-post to always move the lowerextremity of the lever 48 to the same point and thus fixthe position-towhich the swing-plate is carried by contact of the lever with the disk72. Because the rod 6:2 is long as'compared'with the extent of verticalmovement of the jack-carrying slide 18, this movement hasnomaterialeffect uponthe angular position'of the lever 64,(inch-therefore, the swing-plate is unaffected by this alteration in thelocation of the'jack. The extent ofmovement of the swing-plate undertheinfluence of the connecting" mechanism may be adjusted by changing thelocation of the contact-disk 72 upon the thread of the rod36, thusaltering the time at which the contact surface 72 of the fork comes intoeffective co-operation with the disk. Or this movement of theswing-plate may be varied by changing the length of the rod62 by meansofaright and left-handed nut 78 engagingcorresponding threads 80 uponseparated portions of the rod 62.
